The following instructions are for obtaining files by anonymous FTP
(File Transfer Protocol). As a working example, I will use the
example we have done in lab: obtaining the file "starlogo-1.0.sea.hqx"
from the following location: ftp.cs.indiana.edu/pub/fcummins
This example assumes you are using the "fetch" program on a Macintosh.
There are other ways!
-
From the "communications" folder, double click on "fetch" (that's the
dog with the disk in his mouth that looks like a rabid koala bear). A
window will appear. The first line gives the name of a host - that's
the machine which you want to connect to. It suggests
rose.ucs.indiana.edu. This is not the machine you want. Position the
cursor in this line and edit it to read ftp.cs.indiana.edu (no
spaces!). As you are connecting to the machine as an anonymous user,
you do not have to fill in the username or password fields. Just
press return (or click on "OK"). (In lab we entered "anonymous" as a
user name. This turns out not to be strictly necessary).
-
You are now connected to the machine on which the file resides. You
see a list of about 4 directories (folders). Double click on "pub".
A longer list appears. Scroll down to "fcummins". Double click
again. You now see a list of the files in /pub/fcummins. One of them
is starlogo-1.0.sea.hqx. double click on it. This tells fetch that
you want to get the file.
-
A window now appears, asking you where (on your macintosh) you want to
put it. You may save it to the desktop, for later copying to your
student locker, or, if you have logged into your student locker, you
may save it directly there. Click on "desktop" and then, if you are
going to your locker, double click your way into your locker.
Remember, if your locker is on XenonSys, you must open your personal
locker (the one with your user name on it). You are not allowed to
save to anywhere else on XenonSys.
- Now click on save.
What happens next is nothing short of magical. You grabbed one file.
It is an encoded archive file (.hqx = encoded, .sea = archived).
Fetch spots the encoding and unencodes it, giving you
starlogo-1.0.sea. This is one of the things you end up with. Fetch
also spots that it is an archive, and calls a slave called Stuffit,
who unstuffs the archive, giving you a folder called StarLogo, inside
which are several files. The green pizza is the starlogo program.
Click on it to make it work. The two files with big "W"s are
Micorsoft Word documents describing the program. Use Word (in the
word processing folder) to read these. THere is also another folder
containing sample starlogo projects. You can open these from the file
menu inside the starlogo program.
Have fun!!!
